Classification of journals in terms of 70 bi-connected components

based on the citation matrix of the Journal Citation Report of the Chinese Science Citation Index 2001 (991 journals)

See also: (with Jin Bihui,) Mapping the Chinese Science Citation Database in terms of aggregated journal-journal citation relations, Journal of the American Society for Information Science and Technology JASIST (forthcoming).

The methodology is further explained in
